White matter sits underneath the brain’s cortex, or grey matter. In general, white matter damage (WMD) is caused by a lack of oxygen to that part of the brain. </p><p>Periventricular leucomalacia (PVL) is a condition in which decreased blood flow to brain tissue causes it to soften up and eventually die. Although PVL may cause WMD adjacent to the ventricles, resulting in cysts, WMD can occur without cyst formation and also in other areas of the brain for other reasons. </p><p>The range of severity and possible subsequent long-term outcomes from WMD is large. In many cases, the area of damage may be more important than the extent of damage; the various functions of the brain are often controlled by very specific and well defined areas. For this reason, a limited amount of damage in the wrong place can mean lasting and possibly even catastrophic effects. Conversely, some premature babies can recover from extensive damage provided no vital areas are affected. The brain, especially in premature babies, is plastic: if a certain neural pathway is damaged, sometimes the brain can find a new route to send information and commands from one part of the brain to another. </p><p>As with PVL, while WMD may appear on a magnetic resonance imaging (MRI) scan, the effects of the damage may not appear for up to a year. The more severe the damage, however, the more likely it is that the effects will show early. </p><h4>More information</h4><ul><li> <a href="/Article?contentid=1776&language=English">White matter damage (WMD) in premature babies</a></li><li> <a href="/Article?contentid=1846&language=English">Treatment of white matter damage (WMD) in premature babies</a> </li></ul>Diagnosis of white matter damage (WMD) in premature babies
